Hill 10p plates 3 and Fixed grooved guide rails an SllDPOl cecl 011 the sicle plates of the ma and receive nnt1-iriction balls or roll grooved tracks or guide ways '7 on a caritruck 8. A platen frame *9 1s lllGulliQii in the usual manner on the truck and supports a cylindrical platen 10. The carria 'e is thus supported for movement from si e to side of the machine, being propelled from right to left, or in the direction of its feed, by a spring drum 11 connected to the carriage by a band or cord 12. The type bars (not shown) are actuated by finger keys 13 and strike upwardly and rearwardly against the front face of the platen.

Depending lugs 11 are formed on the car riage truck 8. A rms 15 are pivoted to these lugs at 15, the arms being connected to a feed rack 16 which meshes with a feed pinion 17. The shaft of this feed pinion extends through a drum 18 which contains a retarding device for controlling the movement of the carriage when the latter is freed from the control of the eseapement mechanism. The rotative retarding element contained within the drum 18 is connected with a sleeve 19 which surrounds the shaft of the feed pinion, the lower end of said shaft being supported by a bearing screw 20 carried by a fixed part of the machine. A collar 21 surrounds the sleeve 19 and is provided with clutch teeth 22 at the lower edge thereof. This collar is slotted at 23 "for the reception of a screw or pin 24,

threaded into an opening tapped in the sleeve 19. Cooperating clutch teeth 25 extend upwardly from a second sleeve 26 which loosely surrounds the shaft of the feed pinion. A yoke 27 is pivoted at 28 to the sleeve 26 and is provided with a pawl29. A springSO is connected at one end to the yoke-like member 27 and is fixed at its opposite end, as at 31, to the sleeve 26. The pawl 29 is adapted to engage ratchet teeth 32 formed on a hub 33 of an cscapement wheel 34, and it' is by this pawl and ratchet that the} shaft and escapemcnt wheel are coupled turn together in one direction, as will hereinafter appear. A spline block 35 is fixed to the shaft of the feed pinion, which shaft also constitutes the shaft of the escapement wheel. This spline 35 is received in a corresponding spline groove formed in the sleeve 26. The construction is such therefore, that the sleeve 26 is fixed to rotate with the shaft, although said sleeve may receive a vertical movement on the shaft and independently thereof to lift the pawl 29 out of engagement with the ratchet teeth 32,. thus effecting a disconnection between the escapement wheel shaft and the .escapement wheel in order to free the carriage and enable it to travel free from control of the escapement wheel. An elevation of the sleeve 26 is likewise effective to bring the clutch teeth 25 into cooperative relation with the clutch teeth 22, thus ell'ccting an operative connection between the escapement wheel shaft and the sleeve 19 which is operatively connected to the rotative retarding device contained within the drum 18. It follows, therefore, that when the carriage is disconnected from control of the escapement mechanism the retarding device is at the same time thrown into operation to control the speed of the carriage in its movement from right to left. In order to effect an upward movement of the sleeve 26 and to bring about a release of the carriage, I have provided an arm 36 pivoted at its rear end, as at 37, to a post 38 secured to a fixed part of the machine. The forward end of this arm is bifurcated to form a yoke-like portion 36, the two arms of which extend on opposite sides of the sleeve 26. Each arm of the yoke 36 carries an inwardly projecting pin 39, which extends into a circumferentialgroove 4O pr vided on the sleeve 26. An upward movement of the arm 36 is therefore effective to elevate the sleeve 26 and thus effect a release of the carriage in a manner hereinbefore described. The parts thus far described constitute a portion of the No. 20 Yost machine and further description thereof is deemed unnecessary.

The ordinary tabulator mechanism of the I .modifying the structural features thereof as they now exist.

Upwardly and rearW-ardly extending bracket arms 41 are secured to the carriage truck 8. The right-handbracket ll is secured to an upwardly extending lug 42 on the truck by screws 43, whereas the lefthand bracket 41 is secured to the upper face of the truck by screws 44. An upwardly eX- tending foot as is formed on each bracket and these feet formsupports by which the column stop bar is operatively connected to the brackets in a manner which will hereinafter more clearly appear.

The column stop bar in the present construction is in the nature of a double rack bar comprising two parallel rack bars 47, the teeth 48 on one of therack bars extending toward the teeth on the other bar as shown in Fig. 8. These rack bars are united by connecting plates 49 and screws 56 to form a frame which supports the var ous stops which are carried by the carriage. Plate-like column stops 51 are provided at their ends with teeth 52 by which the stops are adapted to engage the oppositely d1s= posed teeth on the rack bars 47. Each platelike column stop extends longitudinally between the rack bars 47 and is provided with a-rearwardly extending contact portion 53, as shown in Fig. 3. These contact or enga ging portions 53 of the column stops are (115- posed in step-like arrangement from one 10 secure the 4 justed LGS 5- column stops in POSl'ulOIIS, I have pm- 021 c p flies are secured headed. had in t w ped openupwer angle piste n which extenfls on the 215506- a forward movepez: ends i0 zipper rm ck buy 4?.

At this time the power of the carriage spring overcomes the power of the springs 72 and 74. As soon, however, as the obstructing stop is moved out of the path of the engaged column stop the springs 72 and 74 will effect a longitudinal movement of the stop carrying bar to the left independently of the carriage until the screws (59 reach the left-hand ends of the slots 68, as shown in Fig. 10, when the stop carrying bar and carriage will again move together as one part. The purpose of this bodily shifting or dis placement of the entire series of column stops with reference to the carriage for a limited distance is to provide for the arrest of the carriage by the same stops at the same letter-space position during both forward and backward tabulation, as will be hereinafter more fully explained.

I have provided on the-frame of the machine a single selecting stop which is cooperative with the different column stops to select a columnar position of arrest of the carriage. The actuating means for this selecting stop is contained within a housing arranged on the right-hand side of the ma chine. In Fig. l the parts are shown with the right-hand cover plate of the housing removed. This housing comprises a plate 76 which is secured to the"right-hand side plate 1 of the machine by shouldered screws 77. This plate supports a shouldered pivot screw 78 on which a bell crank lever 79 is pivoted. The rearwardly extending arm of this bell crank lever is pivoted at 80 to an upwardly extending bar 81 which carries a forwardly projecting selecting stop 82. The forwardly projecting arm of the bell crank lever 79 is pivotally connected to the rear end of a rod 83. The other end of this rod is pivoted by means of a screw St to a slide 85 formed as a part of a selecting key 86. This slide 85 is received in a slot 87 which extends longitudinally fore and aft of the machine in a plate 88 connected by screws 89' tion thereof to the inner side of the slide or ing against the inner face of the plate 88 on opposite sides of the slot 87 therein. The pressure of this spring thei fore is exerted to force the finger piece or key toward the plate 88 and to prevent the slide from being displaced outwardly from the slot. The headed screw 84, which connects the link 83 to the slide 85,-may also be employed to connect the spring 90 to the slide. The

plate 88 is provided above the slot 87 therein with a series,of depressions 92. A detent, which in the present instance is in the nature of a ball 93, is received in an opening 94 in the finger piece 86. This detent ball is pressed into one or another of the depressions 92 by a spring 95, as the ball is brought into register with one or another of. the de pressions. The purpose of this construction is to provide detent means for holding the selecting key 86 against accidental displacement in any one of sixteen difierent positions to which it may be moved and for assuring a proper positioning of the key and slide in each of said positions. The slide may be limited in its movements in opposite directions in the slot 87 by contact screws 96 and 97 threaded into tapped openings in the slide 85 and the heads thereof contacting with the end walls of the slot.

From the foregoing description it will be understood that a movement of the selecting key 86 to any one. of sixteen difiierent positions is effective to produce a corre sponding movement of the bell crank lever 79 around its pivot 78. This movement of the bell crank is effective to raise 91- lower the stop carrying bar 81 to any one or size teen different positions and to bring the stop 82 thereon into register with a contact portion on any one of the sixteen column stops 51. The stop carrying bar 81 under control of the key 86 receives substantially a rectilinear movement in the direction of its length, and during this movement of the bar the stop 82 is not actually brought into cooperative relation with any of the contact portions of the column stops, but s merely set in register with one of them. The movement of the selecting stop 82 into the path of the contact portion of one of the column stops is effected by a rotative movement of the stop carrying bar 81 around its pivot by means to be hereinafter described. The upper portion of the stop carrying bar is guided between parallel plates 98 which are maintained spaced apart by a spacing block 99 (see Figs. 1 and 4) and are connected together by screws 100. One of the plates 98 is formed as a rearwardly projecting flange of a bracket plate 101 which is secured in the frame of the machine by screws 102 (see Fig. 4). The upper end portion of the stop ca'rry ing bar 81 is thus guided for vertical movement and for a. limited 'movei'nent fore and ter my: key acn raby eifeetin ctiim of with a pain Lift from 4 Eli nli

n a ms mecnam the 521 ame tiger n of thus be understood that any one of sixteen different columns may be readily selected with; the aid of the single selecting key 86, and when the releasing key 115 is depressed the carriage will move from right to left until the selected columnar field has arrived at the printing point.

During the arrest of the carriage by the coi l ieration of one of the stops 51 with the selecting stop 82 in the movement of the carriage from right to left, or in the direction of its feed, the carriage will. as hereinbefore explained, move a slight distance independently of the series of column stops 51 after the stop 82- and one of the stops 51 are brought into cooperation. This is due to the pin and slot or lost motion connections 68-69 between the carriage andthe stop carrying bar or frame, as hereinbefore eX- plained. It will be understood that the final point of arrest of the carriage takes place after the lost motion has been taken up, and the extent of this lost motion is indicated in Figs. 9 and 10 by the dotted lines a and b. The distance between these lines indicate the extent of lost motion or movement of the carriage effected after the stops are brought into coiiperation. The purpose of this feature of the construction is, as has been previously pointed-out, to enable the carriage to be arrested at the same letter space position by the co'dperation of the same stops during both a backward and a forward tabulation. If, forexample, a: backward tabulation is to be effected, the selecting key 86 is moved fore andaft of the machine, to set the stop 82 to arrest the carriage at a given columnar field, determined by such setting of the stop. The operator then depresses the key 115, at the same time giving a slight lateral pressure of the key to the right and thereby arresting the key through the cooperation of the lever 112 with the shoulder 119 on the guide plate 11 1. The limitation of the depression of the key 115 thus effected results in moving the stop 82 forwardly into coiiperative relation with the registering projection on one of the column stops to the leftof the stop 82. \Vhile the limited depression of the key 115 is effective to move the stop 82 forwardly into operative position, it is ineffective to release the carriage from the control of the escapement mechanism. This is due to the fact that there is sullicient lost motion between the levers 36 and 122 (see Fig. 4) to enable the limited depression of the key 115 to be effected without throwing the sleeve or clutch member 26. It follows, therefore, that although the stop 82 has been moved to operative position the carriage will remain under control of the escapement mechanism to hold it against movement in the direction of its feed. The

,operator may, nevertheless, move the carriage by handat this time from left to right position.

until it is arrested by the cotiperation of the stop 82 with the selected column stop.

Fig. '10 shows the positions of the parts at the instant a column stop 51 co-acts with the projected selecting stop 82 during the backward movement of the carriage. It will be seen that at this time the screws 69 are in the left-hand ends of the slots 68 so that there is no relative movement between the carriage and the stop carrying bar or frame when the carriage is arrested during its movement from left to right. The point of arrest, therefore, will be at a position indicated by the dotted line a in Fig. 10. The escapement mechanism being operative or effective at this time, the carriage will be prevented from moving in the direction of its feed, thus holding the carriage in the position at which it has been arrested by the cocperation of the stops. A release of the key 115 at thistime withdraws the stop 82 from the path of the co-acting projection 53 on the column'stop and an arrest of the carriage is thus effected at the selected columnar field. If, on the other'hand, the

arrest of the carriage is effected by these same stops 82 and 51 during the movement of the carriage from right to left, a movement of the carriage independently of the stop bar will be effected after said stops are brought in contact. The distance of such independent movement corresponds to the distance between the dotted lines a, b in Figs. 9 and 10, and this distance corresponds to the thickness of the contact portions of the two co-acting stops 82 and 51. It will be understood, therefore, that the arrest of the carriage by these stops during the movement of the carriage from right to left compensates for the thickness of the co-actin'g' stops so that the final arrest of the carriage by the stops will be at a point indicated by the dotted line a instead of,at the line 'b where they are first brought into engagement. This line (1 indicates the same point of arrest by these co-acting stops during the movement of the carriage from left to right so that in both instances the carriage will be arrested at the same letter space Otherwise stated, the carriage is arrested by the stops 82 and 51 during the movement of the carriage from left to right without any lost motion being efiected between the carriage and the stop carrying bar, the point of arrest being indicated by the dotted line a through the cooperation of the right-hand face of the contact portion of the column stop 51 with the left- I hand face of the projcctedselecting stop 82. On the other hand, during the movement of the carriage from right to left, the lefthand face of the engaging portion of the column stop 51 will co-act with the righthand face of the projected selecting stop 82. But after this engagement is effected cupying the sixteen denominational positions of arrest that may be selected under the example shown. The index plate 126 may be provided with a series of indices in the spaces 131 at the left-hand portions thereof to designate the pounds, shillings and pence arrangement referred to above, or any suitable inscriptions may be made on the index plate to correspond to the sixteen diii'erent denominational positions of arrest aflorded by the cooperation of the selecting stop 82 with the stepped step 133.

F romthe foregoing description it will be understood that I have provided simple and efficient means by which a large number of columns may be selected during a single travel of the carriage; that the stop 821s movable transversely of the paths ofmovement of the contact portions 53 to set the stop 82 into register with the contact portionof one or another stop 51; thatthe key 115 is operative to move the stop 82 into and out of cooperative relation with the registering contact 53; that the construction is such that the tabulating mechanism is automatically rendered operative at one time as a column selector and at another time as a denominational selector, as determined by the position of the carriage in its line of travel; that the relative adjustment f the stops 51'and 133 determines at what point in the travel of the carriage the tabulating mechanism shall be operative or effective for one character of selection and not for the other, and also determines whether the tabulating mechanism shall be operative first as a column selector and then as a denominational selector or vice, versa; that the employment of one character of stops 51 or 1.33 to the exclusion of the other determines whether the tabulating mechanism shall be operative exclusively and indefinitely as. a column selector or as a de nominational selector and that the same keys 86 and 115 and the same stop 82 are operative at one time for column selection and at another time for denominational selection.

I am aware that various changes in the construction may be made Without departing from the spirit and scope oi my invention and it should be understood, therefore, the accompanying drawings illustrate but one form of construction embodying and illustrating my invention. Moreover, it should be understood that various features of the construction maybe employed without others.
